Application filed September 8, 1913. Serial No. 788,679,

To all whom t may concern Be it known that we, VICTOR ANGERER and ARTHURB. DAVENPORT, J r., citizens of the United States, and residents ofRidley Park, county of Delaware, State of Pennsylvania, andPhiladelphia, county of Philadelphia, State of Pennsylvania,respectively, have invented certain Improvements in Tongue- Switches, ofwhich the following is a specication.

One object of this invention is to improve the construction of a tongueswitch of the type in which a portion of the body of a switch structureextends over a portion of the heel or pivot of the tongue.

Another object of the present invention is to provide a substantial basefor the pivot portion of the tongue and to provide an adjustable baseand means for yieldingly holding the pivot of the tongue to the base.

In the accompanying drawings :-Figure 1, is a plan view of sucient of atongue switch structure to illustrate our invention; Fig. 2, is asectional view on the line a-a, Fig. 1;.Fig. 3, is a transversesectional view on the line -J), Fig. 1; Fig. 4, is a sectional plan viewon the line 0 0, Fig. 2; Fig. 5, is a sectional view similar to Fig. 2,with the tongue removed; and Fig. 6, is a detached perspective view ofthe rear portion of the tongue of the Switch.

Referring to the drawings, 1 is the body of the switch structure.

2 is the tongue resting on the depressed portion of the body, asillustrated in Fig. 2, and having a depressed pivot 8, in the presentinstance below the plane of the surface 4 of the body upon which themain portion of the tongue rests.

5 is an integral portion of the body extending over the depressed pivotof the tongue, as illustrated in Fig. 8.

The pivot 3 of the tongue ts into an annular bearing 15, the frontportion of which is reduced in depth at 17, so that, by raising thetongue to the extent of the space 18 between the underside of theintegral portion 5 of the switch body and the upper part of the pivot 3,it will be clear of the circular bearing and can be drawn forward inorder to remove it from the body through the opening between theintegral portion 5 and the vertical wall 19. The pivot further rests onthe circular base 6 adjustably secured to the body of the switchstructure, so that, when the main portion ofthe tongue rests on thesurface 4, the base can be brought into simultaneous contact with thebottom of the pivot. In the present instance, this base is in the formof a screw plug having a coarse thread 7 adapted to a similarthread 8 inthe switch structure and after the plug is in `place moltenrlead, orother metal, is poured into the space between the two threads, asindicated by dark lines, Fig. 2, so as to hold the two parts firmlytogether after they' have been properly adjusted in relation to eachother. The base can be adjusted by a suitable tool, which can engage thelugs 20 on the interior of the base.

In order to hold the pivot 3 firmly on the base, we provide a spring bar9, which extends laterally from one side of the opening to the other andrests in an inclined position against the inclined wall 10 of the pivot3; being engaged at one end by a lug 11 cast integral with the structure1, and at the other end being secured to a rib 12 by a bolt 13 having anut 14 which is adjustable so as to regulate the pressure of the springplate on the pivot 3. Thus, while the switch tongue can be turned, thetendency of the spring bar is to hold the pivot firmly on its seat orbottom bearing 6.

The spring plate 9 not only tends to force the pivot down onto the base,but it also Patented Jan. 1e, i914.

forces it against the rear portion of the circular bearing 15, making anexceedingly simple and substantial construction which will give a fullbearing for the pivot of the tongue. The spring plate 9 extends into abox 16 formed in one side of the switch structure and in this box islocated the bolt 13 and its nut 14. The box is preferably provided witha suitable cover and, when the cover is removed, access may be had tothe box to Yadjust the spring plate or, by detaching the bolt, thespring plate can be bodily removed from the box, after whichy the tonguecan be detached by raising it, so that the pivot will clear the portion17 and moving it forward so as to allow the pivot to pass fromunder theoverhanging extension 5. f

By the abovev construction, the pivot is also held on the base by theannular bearing so that, in the event of the'spring plate becomingloose, the-tongue cannot shift forward.

l. rThe combination in a railway switch,

of a body portion having a pvot opening and an annular bearing locatedbelow the pivot opening; said body also having an integral overhangingportion extending over the bearing; and a tongue having a depressedpivot arranged to pass under the overhanging'portion of the structureand to tit in the annular bearing.

2. The combination in a switch, of a body having a recess and an annularbearing located in the recess, said body port-ion having a portionoverhanging the annular bearing; a tongue having a depressed pivotarranged to pass under the overhanging portion of the body; and avertically adjustable base, within the bearing, on which the pivotrests.

3. The combination in a switch structure, of a body portion having arecess and having an integral portion extending over a part of therecess; said body portion having an opening therein directly under theoverhanging portion and said body portion having a screw thread; a baseplug also having a screw thread meshing with the thread of the bodyportion of the switch structure; and a tongue having a depressed pivotarranged to pass under the overhanging portion of the structure and torest upon the adjustable base.

4. The combination in a switch structure, of a body portion having arecess to receive the switch tongue and having an overhang ing portionat the pivot of the tongue; the body also having an annular bearing; anadjustable base within the bearing; a tongue having a circular pivotdepressed and eX- tending at the rear thereof and under the overhangingportion, the front wall of the pivot being beveled; a transverselyarranged diagonal spring bar resting on the beveled portion of thepivot; and means for adjusting said bar so as to force the pivot againstthe base and against the rear of the circular bearing.

In ktestimony whereof, we have signed our names to this specification,in the presence of two subscribing witnesses.
